I think a category element could be useful, but I have a few questions first:
> It's widely-deployed in practice, Where? Any examples of its use by producers? Any examples of its use by consumers? What categorization schemes are in use with RSS 2.0? Are all common categorization schemes compatible with the provided structure? (hierarchy, tagging etc) Are all common categorization schemes compatible with the slash delimiter? What is the significance of the order of the keywords (if any)? Cheers, Danny. -- http://dannyayers.com
